title: Monoclonal antibody-based immunoassays.
abstract: An immunoassay may be defined as an assay that employs an immunological reagent, usually an antibody, to confer specificity for the ligand being measured. As a corollary to this, the discovery, and subsequent development, of monoclonal antibodies (MAbs) has greatly expanded the application and use of immunoassays. Polyclonal reagents, with their associated problems of specificity and quality control, have now been largely replaced by readily available MAbs of potential immortality and well-defined specificity and affinity. This has resulted, in the last two decades, in a great expansion in the range of immunoassays available and also a significant improvement in their reproducibility and reliability.
